“Move right, move left, move up, move down,” the Pixel said. When my finger was right on the fingerprint icon, the phone would say “fingerprint sensor window” and would tell me to press down firmly on the screen. If the fingerprint scanner unlocked the phone, the device would say, “Phone unlocked.” Remember, my eyes were closed as I was trying to see if a person with limited vision could unlock their device with this feature. It certainly seems that way.
Android users with a handset running an older version of Android can only receive the audio feedback when they are registering their fingerprints on their phones. With Android 15 beta 1, this feature will work when TalkBack is activated and the device user wants to unlock his phone using the under-display fingerprint scanner. To enable TalkBack, go to Settings > Accessibility > TalkBack and toggle on the feature.

We can’t think of any reason why Google wouldn’t keep this feature when the final version of Android 15 is released later this year.
